Abstract

The utility model provides a displacement device for the circular loom. After each opening moves, the inner part of the healds of a part of the heald pairs are meshed to cause partial healds to make a timely across corresponding conversed displacement for the reciprocating displacement of a leno line; the leno line is vertically parallel with a core line and the two adjacent meridians. A part of the meridians of a part of the heald pairs are freely led by a lead device to form a shuttle way, and form the side change at other partial healds. After the back of each woof, as the healds are against with each other along one or other directions, a primary pulling force is generated at the meridians; at the zero way of the heald, due to the reciprocating movement, the meridians are made to hop up to the other side of the other meridians to form the leno.

Description

Circular loom

The present invention relates to contain and arranged the circular loom of composition two rows circularly round the interior and outer branch heddle (heald) of loom main shaft, these minutes, heddle (heald) was arranged in pairs a part with the warp thread piece that guides two annular spread, and this part warp thread piece is given anti-phase up-down alternative motion by the loom main shaft of rotation and weaved or turn round shed open with formation.

In the fabric that weaves on looms out, so-called LENO AND GAUZE has special meaning, in LENO AND GAUZE, two adjacent warps are no longer parallel to each other, parallel are constrained can not slide but so-called leno threads correspondingly passes through other warp (being bottom line) in this manner here.

Therefore, just want for a long time on circular loom, also can produce this LENO AND GAUZE, particularly be used to make the tubular woven fabric of sack, but can't or can not realize satisfactorily so far with narrow plastic strip production.

Here the problem of Kao Lving is to arrange in which way and guide these anti-phase branch heddle (heald)s that moves up and down, and makes two interactional warps can do back and forth mutual the displacement each after forming the alternating movement of shed open.

The objective of the invention is on the circular loom of existing type, to weave out LENO AND GAUZE.

According to the present invention, task is to solve like this, for the leno threads of the warp that makes two close neighbours is back and forth arranged with the production LENO AND GAUZE along the length direction of bottom line, shift unit meshes a pair of minute at least one branch heddle (heald) in the heddle (heald) after each opening traverse, to produce the instantaneous horizontal relative backward shift position of the required branch heddle (heald) of the reciprocal displacement of leno threads; The warp of a branch heddle (heald) in a pair of minute heddle (heald) is freely guided forming shed open by the line guiding device, and realizes the side conversion on another minute heddle (heald).

So just can the per pass parallel by later on by those minutes heddle (heald) produce an initial tension on these line lines towards one or another direction superior displacement relative to one another, this just causes these warps to jump on the another side of another warp in divide combining the alternating movement of passing zero traverse back at every turn, thereby makes LENO AND GAUZE.

In order mechanically to guarantee this purpose, preferably when these minutes, heddle (heald) supported the comb shape guiding device of these warps, the opening that the tooth of this guiding device or prong respectively have a line eye to be arranged in and be used as warp on its free end guides, and formation lead seam is used for freely guiding warp to realize the side conversion between each adjacent teeth, and therefore the heddle (heald) of a pair of minute heddle (heald) need support the comb shape guiding device of arranging relative to one another.

In order to prevent warp wire jumper alternately, it can be favourable being fixedly mounted in the gap that branch cut water on the framework extends in the comb shape guiding device.

In this respect, the comb shape guiding device can be contained on the guide rod, also can be arranged in the gap that constitutes on crack interior bar or the outer bar that divides the right tape of heddle (heald).

This will have structural advantage, if divide the displacement of these comb shape guiding devices of heddle (heald) to cause the laterally relative backward shift position of these minutes heddle (heald) in these.

Here, the transverse shift of comb shape guiding device can be realized along a horizontal guide or by a shaking bearing.

In addition, if the instantaneous laterally shift unit relative to the backward shift position of comb shape guiding device has the rocking bar that can be swung by the cam actuated of rotating round main shaft in the traverse of minute heddle (heald) is moved, or having the ratchet that moves and operate by the traverse of minute heddle (heald), this will be suitable.

As from the foregoing, the circular loom that draws like this is also production LENO AND GAUZE effectively from now on, and the measure of being taked is particularly suitable for reequiping existing circular loom and do not need to go to great pains gas and big expense.

In addition, the support 9 that is used for the cloth ejector is contained in this loom base 1, and this support also comprises the transmission device 10 of this cloth ejector, also has cloth carry-over

pinch rolls

11 and 12 and fabric bundle 13.A fabric Stent 14 also works in draws in the zone.

Also have, shown in circular loom on, as seen be not shown specifically to the warp that is positioned at left or through the feeding roller 15(of bar) and be positioned at the feeding roller 16 of right-hand warp 50,51, in addition, what also be useful on these warps arranges roller 17.These warps or be divided into the warp thread piece of circular arrangement through bar 50,51, and draw (not being shown specifically) from many groups bobbin in a known manner.Weave race in order to form, described warp thread piece by these minutes heddle (heald) 6,7 lift, and the another one warp thread piece is driven downwards from the height of weaving the plane by the motion of so-called shuttle changing road, forms on the warp race under race and the warp.Between these races, at least one, normally several shuttle 30 that has the weft yarn bobbin passes on horizontal route.Because the circular motion of shuttle, parallel 52(Fig. 8 that unwinding is come out from the weft yarn bobbin) be transferred on the edge of the tubular woven fabric manufactured, so this weft yarn can be knitted in the fabric.Then, tubular woven fabric just can be drawn close up flat.

The transmission of these shuttles 30 is by realizing on this main shaft 8 that is positioned at loom and with the tabular cam 33 that it rotates together that this tabular cam comes to engage with these shuttle places of working by actuation member.In addition, this main shaft 8 this supporting one second tabular cam 33 ', it is connected with 47 places of working with so-called shaft road 46 by a plurality of rocking bars 36 that radially are provided with round this cam and 37, these shaft roads 46 and 47 with common mode with the shuttle changing road move be delivered to these minutes heddle (heald) 6 or 7 on.

In another embodiment of above-mentioned this circular loom, the also available tape that cracks of these minutes heddle (heald) is made, to these tapes, to almost each divides heddle (heald), there is an endless belt 26 striding each deflector roll 29 of on corresponding upper and lower frame part, supporting rotatably and stretches.(Fig. 7).The interior bar and the outer bar of band respectively carry the line eye, draw a warp that belongs to or another warp thread piece by each line eye.These of this band anti-phase pumping that is produced makes two warp sheets that above-mentioned shuttle changing road motion take place.Shuttle changing road motion hereto, known preferably should in bar this line now face be fixed on the so-called heddle (heald) carriage, this carriage vertically slides up and down in guiding device.

Deflector roll stretches out from these vertical slide, and these deflector rolls are resisted against with it on the corresponding cam face of the plate cam that cooperates, this tabular cam be contained in one heart on the main shaft of loom and can and it rotate together.

The structure of the top circular loom of addressing is corresponding to prior art, so do not need to be further described below.

Here the problem relevant with above-mentioned circular loom that will deal with will develop this circular loom exactly, makes it to make the LENO AND GAUZE as this paper introduction part is said.

In order to realize this possibility, just need be after the per pass parallel passes through, by these minutes heddle (heald) 6 and 7 relative to one another along or another direction displacement and at these warps 50, produce initial tension on 51, this just causes these warps to divide the returning in zero traverse of alternating movement of heddle (heald) to jump on the another side of another warp each, thereby makes LENO AND GAUZE.

This LENO AND GAUZE, the leno threads 51 that wherein interweaves and bottom line 50 these two close neighbours' warp is lived by many parallel 52 constraints, can not slide, as shown in Figure 8.

Therefore, for the leno threads 51 of the warp 50,51 that makes two close neighbours is back and forth arranged to produce LENO AND GAUZE along the length direction of bottom line 50, shift unit is engaged on the branch heddle (heald) on 6,7 the interior minute heddle (heald) 7 after being preferably in each opening action, to produce instantaneous laterally relative backward shift position.Also have, the warp of the right branch heddle (heald) of this minute heddle (heald) is at every turn all by wire installation 24(Fig. 3) freely guide to form opening, on another minute heddle (heald), then realize the side conversion, as at the more detailed Fig. 3 that shows continuously, in 4 and 5 like that.

Therefore, these minutes heddle (heald) 6,7 are supporting these warps 50,51 comb shape guiding device 22, the opening that the tooth of this guiding device or prong 23 respectively have a line eye 24 to be disposed in and be used as warp on the free end guides, and the lead seam that is formed between each tooth and its adjacent teeth is used for freely guiding warp to realize the side conversion.In this respect, this development is to make right this minute heddle (heald) of this minute heddle (heald) 6 and 7 support to be arranged to comb shape guiding device 22 respect to one another, and they here are contained in respectively combines on the bar 46 and 47.

In any situation, the separation tongue 610 that is fixedly mounted on the framework is stretched between the lead seam 25, as shown in Figure 5.These separate tongue and prevent the alternately hand pick between the warp.

In this respect, this minute heddle (heald) 7 comb shape guiding device 22 to make movably be favourable, by for example horizontal guide 27 this comb shape guiding device 22 is contained in corresponding combining on the bar 47 for this reason.Driven member on corresponding guiding device 22 just can be driven with the contacts of tabular cam 33 odd-jobs in the rotation of circular loom (Fig. 1), these driven members corresponding guiding device 22, for example, the effect of keeping out back-moving spring laterally is shifted, until disengaging work contact once more, when this guiding device 22 is retracted in the opposite direction by this spring (not shown) till.

At Fig. 3, in 4 and 5, can be readily seen that, these minutes heddle (heald) 6 and 7 and comb shape guiding device 22 motion of producing according to LENO AND GAUZE shown in Figure 8.

When, for example, be in respect to these warps of the so-called zero-bit of these minutes heddle (heald)-on this position and weave in the plane (Fig. 3)-this minute heddle (heald) 7 and move upward and when this minute, heddle (heald) 6 moved downward, bottom line 50 at first was in the left (Fig. 4) of leno threads 51.After the motion change, this minute heddle (heald) 7 be in downward state and this minute heddle (heald) 6 be in upwards state, after parallel inserts, the comb shape guiding device 22 generation displacements to the right that should interiorly divide heddle (heald) 7, therefore, these warps 50 and 51 are accepted an initial tension, make these warps 50 and 51 change the limit owing to jumping over when zero passage next time, as shown in Figure 5, Fig. 5 shows the motion change of having finished.Therefore, this bottom line 50 is in the right side of this leno threads 51.When moving together down, this comb shape guiding device 22 of branch heddle (heald) 7 can be got back to its another (left side) extreme position in this under the effect of this back-moving spring, and this causes these warps 50 and 51 side conversion with regard to another, and replaces down like this.

At minute heddle (heald) 7 " on comb shape guiding device 22 ' usefulness shaking bearing 28 as shown in Figure 6 produce transverse shift, can obtain same effect.For this purpose, one has rocking bar 61 percussion device 63 and 64, that also swing round axle 62 in the horizontal direction, extend in and divide heddle (heald) 7 in each " below; these percussion devices 63 and 64 alternately swing in its lower section when each divides heddle (heald) to move downward at every turn, this comb shape guiding device 22 ' at every turn is all from a side towards the opposite side tilting and conversely thus.The swing of this rocking bar 61 is to realize by the cam part 60 that the tabular cam 33 with loom engages.

Another embodiment according to device of the present invention can infer from Fig. 9 to 11, and Fig. 9 and 10 illustrates round two different operating positions at a minute heddle (heald) frame 7 " ' on the comb shape guiding device 22 installed of shaking bearing 28 " ' swing or tilting.For this reason, have a ratchet shaft of supporting regularly 95, it is near dividing heddle (heald) 7 accordingly " ' flatly stretch; This ratchet shaft is supporting to have the control cam wheel 94 of three cam part 93 here.These control cams 93 of working together with ratchet 96 are from this comb shape guiding device 22 " ' on stretch out by this way; make this comb shape guiding device 22 " ' in the moving downward of each traverse by tilting towards a side or opposite side, stop device 77 is limiting this basculating movement.Have best work to connect (Fig. 9 right side), realize jumping over (Fig. 9 left side) on the other hand between this cam part 93 and this ratchet 96 in order to make on the one hand, this cam part 93 and this ratchet 96 have the clinoplain according to the shape of Figure 11.In addition, a ratchet 90 is contained in this ratchet shaft 95, and this is taken turns with 91 places of working of blocking and is connecting, and this ball 91 gives by one and adds stress spring 92 loadings.This is blocked and 91 can do waving so that cause or another cam part 93 can skip corresponding ratchet 96 and the calibration of control cam wheel is produced of certain angle reverse at the bottom of the tooth of ratchet 90.

In addition, its minute heddle (heald) 6 ' and 7 ' in a manner described circular looms that as Fig. 7 at length illustrates, constituted by bar or tape 26, just can press the same manner use through small structural change.In the case, in this, divide heddle (heald) or bar 7 ' on this comb shape guiding device 22 "; in order to be shifted, can be bearing in a horizontal guide rail 27 ' go up or also can be bearing in according to as on Fig. 6 or Fig. 9 and the 10 shaking bearings the foregoing description that is limited, that have shift unit (Fig. 7 is not shown).
